4SPECIFICATION formingpart of Letters Patent No. 275,683, dated April10, 1883.

Application filed November 21, 1882. (No model.)

To all 'whom it may concern.-

Be it known that I, EDMUND D. MEAGHER, of South Bend, in the county ofSt. Joseph and State ot' Indiana, have invented a new and usefullImprovement in Plows; and I do hereby declare that the following is afull, clear, and exact description of the same.

My invention relates to plows, and is an improvement more especiallyupon the form of plow shown in Letters Patent granted me on lthe 17thday of February, 1882, No. 253,408.

The object of my invention is to simplify the construction and tofurther strengthen the parts where weakest in the respects hereinafterexplained, to the end that my improved plow withindependently-reversible point and wing may be constructed as cheaply asan ordinary plow without impairing its necessary strength or departingfrom the simplicity required in use.

The irst part ot'- my invention consists of an improvement in the footof the standard and in the reversible point litted thereto. The secondpart relates to means for strengthening the foot of the standard at apoint where the hooked bolt passes through it to draw back and hold thepoint.

In the drawings, Figure 1 represents a bottom view of a plow embodyingmy improvements. Fig. 2 is a side View of the land side of the plow.Figs. 3 and 4 are detached views of a portion of the foot of thestandard. Fig. 5 is a-de'tail of the point and wing; Fig. 6, a detail.

In my said patent the bearing-piece for the point, which passed throughthe opening in said point, was not made to extend quite to the surfacethereof, so as to be llush with the surface of the point and landside.The side of the point, as shown in Fig. 4 of the said patent, wasadapted to receive a plate, as shown -in Figs. 1 and 5, which platecovered the otherwise exposed face of that part of the standard uponwhich the point rested.

1n my present invention I simplify the construction by extending thepart which supports the point to bring it flush with the surface of theside of the said point, whereby it is made to lill the whole recess andpresent a smooth surface on the land side. I thus dispense with thecoverin`gplate and simplify the form of the point, thus rendering iteasier to fit the parts and reducing the expense. The lateral projectionwhich forms the bearing for the point is shown at a in Figs. 2 and 3. Itis cast so as to exactly it the recess in the point A. This point is inall respects like that shown in my said patent, excepting that it is notrabbeted to receive the plate, -and that the web 1 in the presentimprovement is of the same width as the upper and lower anges, 2 2. Theedge of the web 1, when the point is in place, is therefore flush withthe landside and with the outer surface of the part a.. The hook-bolt 7,which holds the point in place, passes through the hole 16 in thevertical flange on the side of the standard-foot, and projects in frontof the web 1, one corner of the part a being slightly rounded out toreceive the hooked end, as shown in Fig. 2. The foot of the standard issomewhat weakened by the hole 16, and this and the form required inorder to give place to the hooked bolt have rendered it necessaryheretofore to make the standard of malleable iron, which has increasedthe expense of this construction. In order to obviate the diiiculty, Ihave devised the form shown in Figs. 3 and 4, in which a bridge, 17, isthrown across from the vertical ilange 18 of the standard-point to thebottom plate, 19. This leaves a cavity, 20, for the hook, the bridgeextending forward and covering the whole cavity to the point and edge ofthe bot tom plate. This gives all the necessary strength for the foot ofthe standard and makes it prac ticable to cast the standard of commongray iron. It does not practically increase the weight ofthe plow whenin use, as the cavity in the previous construction is usually filledwith dirt.

. In my former patent heretofore referred'to the wing C was joined tothe point by means of a tapering bevel fitting into the recessed sidesof the point. I iind that this construction can be advantageouslysimplified by 'shaping the edge of the point with a plain surta-reproperly inclined 'to abut squarely against the rplain edge of thepoint, the upper and lower surface of the point bein grounded off, asshown at 21, Fig. 5. In all other respects the plow shown is of the sameconstruction as that dethe projection adapted to receive thereversiscribed in my aforesaid patent.

Having thus described my invention, what I claim is- 1. A lateralprojection, a, upon the end of the standard, in combination with thereversible point A, the said projection fitted to the recess in saidpoint, and being ush with the side thereof when the point is in piaceupon the foot of the standard, substantially as described.

2. The standard-foot, as described, having ble piow-point, a holeadapted to receive the hooked rod to hold the plow-pointin place', 15andthe strengtheninghridge l7,substm1tially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

EDMUND D. MEAGHER.
